SWIVEL PIPE-COUPLING.

SPECIFICATION formingipartiof Letters Patent NoA 353,154, dated November23, 1886.

Application ledJulykl, 1886. Serial No. 205.779. (No model.)

To L ZZ whom. izmay concern: v Be it known that I, HARRISON S. MILLER, acitizen ofthe United States, residing at lndianapolis, in the county ofMarion and StateA of Indiana, have invented a new and useful Improvementin Swivel Pipe -Couplings, of which the following is a specification.

My invention relates to an improvement in that class ofpipe-couplingswhich are used for 1o coupling hose to water supply pipesfor sprinkling purposes about private residences.

The objectof my improvement is to provide a swivel-coupling which may becheaply constructed offew parts,and which may be quickly I5 andconveniently secured to the water-supply pipe.

The accompanying drawings illustrate my invention.

Figure l is a central vertical section. Fig.

zo 2 is aplan.

A is a hollow coupling' having an interiorly screw-threaded socket, a,adapted to engage the supply-pipe B, which makes a tightjoint againstthe gasket c. The upper end of coupling A is semi-spherical andterminates in a solid cylindricalstem, the upper end ofwhich is squaredto receive the thumb-wrench c.

Ois a hollow chamber fitting nicely over stein d and that portion ofcoupling A immediately above the socket a, so as to turn thereon.

Chamber O is provided with an interior annular shoulder, f, betweenwhich and a similar shoulder, g, on the coupling A is a soft packing, h.The outside of the upper semispherical portion of coupling A is smallerin diameter than the inside of the upper portion of chamber O, and theinterior of the coupling communicates with the interior of the chamberthrough several openings, t, in the walls of 4o the coupling. A branchpipe, j, formed inte` gral with chamber C and communicating with itsinterior, is screwthreaded to receive the ordinary hosecoupling. k

The thumb-wrench e has a central hub, k, in 4 the upper part of which isa square opening, l, which dts over the square end of stern d, and thelower part forms an annular iiange, m, Which enters a recess, n, in theupper part of chamber O, and forms, with the packing 0, a 5( stuiiingboxwhich prevents leakage about stein d, the wrench being secured to thestein and forced down upon the packing by ascrew, p. When thus secured,chamber O is free to turn upon (he coupling A, andthe water passes vfrom the supply-pipe through the coupling into the'chauiber and outthrough the branch pipe j.

The abovedescribed swivel coupling, con- 6o sisting ofthe hollowcoupling A, having socket a, shoulderg,ste1n d, and openings t', chamberO, having shoulderfand recess n, branch pipe j, the thumb-wrench c,having ange m, the

packing 0, and packing h, all combined substantially as speciiied.
